Sunday EX Erik Elstran BMX Bike Description:
The Sunday EX BMX Bike in Toothpaste is the signature bike of pro rider Erik Elstran, known for his wildly creative riding. Built to deliver pro-level performance without the high-end price tag, the EX features a full 100% chromoly frame, including Sunday’s iconic wave downtube for added strength and dent resistance. It’s equipped with a solid mix of aftermarket Odyssey and Sunday parts, including the Odyssey C5 cassette hub—configured for Right Hand Drive but easily switchable to Left. Removable brake mounts give you the option to keep things clean and brakeless. Just like Elstran’s riding, this bike is all about pushing limits and having fun.
This Erik Elstran cassette version comes with a 21" toptube which is ideal for riders in the ballpark of 5'8" to 6'2". Sunday offers a Julian Arteaga freecoaster version in Iridescent Pearl Colorway that features a 20.75" toptube, ideal for riders 5'6" to 6'.
